SP-100 (Space reactor Prototype〔''(Acronyms: SP-100 means Space reactor prototype )''〕) was a U.S. research program for nuclear fission reactors usable as small fission power systems for spacecraft. It was started in 1983 by NASA, the US Department of Energy and other agencies.〔''SP-100, the US Space Nuclear Reactor Power Program,'' Technical information report. Available at (Energy Citations Database )〕 A reactor was developed with heat pipes transporting the heat to thermionic converters. It was cooled with lithium. The project never advanced to flight hardware and was terminated in 1994.〔 〕 == See also == * Systems Nuclear Auxiliary Power Program and SNAP-10A, that flew in 1965 * Safe Affordable Fission Engine, a later project 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「SP-100」の詳細全文を読む スポンサード リンク
